Abstract:
Bacterial infection is a problem in the intensive care unit (ICU). We conducted the present study in the surgical ICU over a period of 5 months to determine the prevalence of nosocomial infection. Our ICU has a bed strength of 7 with an average occupancy rate of 5.46 patients. Mechanical ventilation associated pneumonitis was the commonest nosocomial infection. Older patients, patients with organ system failure and patients with co-morbid conditions were at high risk of developing nosocomial infections. E. coli was the commonest and most resistant organism grown in our study.
Insights
Nosocomial infections are common in surgical intensive care units (ICUs). Mechanical ventilation-associated pneumonia was the most frequent infection, with E. coli being the most resistant bacteria.
Area of Science:
- Critical Care Medicine
- Infectious Diseases
- Hospital Epidemiology
Background:
- Bacterial infections pose a significant challenge in intensive care units (ICUs).
- Understanding the prevalence and patterns of nosocomial infections is crucial for patient outcomes.
- Surgical ICUs are particularly vulnerable due to the critical condition of patients.
Purpose of the Study:
- To determine the prevalence of nosocomial infections in a surgical intensive care unit.
- To identify the most common types of nosocomial infections.
- To characterize the microbial agents and their resistance patterns.
Main Methods:
- Prospective study conducted over 5 months in a surgical ICU.
- Data collection on patient demographics, comorbidities, and infection types.
- Microbiological analysis of common pathogens and antibiotic susceptibility testing.
Main Results:
- Mechanical ventilation-associated pneumonitis was the most prevalent nosocomial infection.
- Older patients, those with organ system failure, and comorbidities were at higher risk.
- Escherichia coli (E. coli) was the most frequently isolated and resistant organism.
Conclusions:
- Nosocomial infections, particularly ventilator-associated pneumonia, are a significant concern in surgical ICUs.
- Risk stratification for infection should consider patient age, organ failure, and comorbidities.
- Effective antibiotic stewardship is essential due to the prevalence of resistant organisms like E. coli.
